Group rectangles

[antofa]

16 berserkers found, but actually 7 is in inventory

Seems you don't group rectangles with cv2, do you?

For example:

def get_rectangles(image, template, THRESHOLD = 0.8):
    result = cv2.matchTemplate(image, template, cv2.TM_CCOEFF_NORMED)
    yloc, xloc = np.where(result >= THRESHOLD)

    rectangles = []

    [ht, wt] = template.shape
    for (x, y) in zip(xloc, yloc):
        rectangles.append([int(x), int(y), int(wt), int(ht)])
        rectangles.append([int(x), int(y), int(wt), int(ht)])

    rectangles, weights = cv2.groupRectangles(rectangles, 1, 0.1)

    return rectangles

Could you explain what does it do exactly?

As far as I understand, it should eliminate possible overlapping rectangles?

It's also interesting that it's first time I'm seeing the algorithm detects the same inventory item as multiple matches. Could you provide a little bit more info about your setup?

yes, it is for groupping close rectangles

windows 10, also i dont know what is correct scale rate for my window (1920x1040 paint says, but in poe 1920x1017)

The support for the windowed version should arrive soon. Hope it will help it your case.

@antofa, I've added the implementation for rectangle grouping in 65bb088. Could you please take a look and validate that the code is correct? After that, I'll close this issue.

@4rtzel perfect, it works without errors

This issue is resolve. Closing.
